trying to lower with ez chassis s10 kit

[Mgicm]

Picked up a 50 3100 half ton on s10. has ez chassis kit. there are dropped spindles on front and what looks to be a block kit on the back. the block looks HUGE like 4 inches.

Some stupid questions.

Is the bigger the block on the rear the more of the drop or the other way around?

It seems the ez chassis kit stands the cab a bit off the frame. I think there are two options when buying the kit. Not sure which this one has but it sure seems to stand off the frame a bit.

how can i the body lower than it is now?


thanks!
